Way too swingy. If it succeeds and you have any kind of board, you’re way ahead because your board can suddenly tank AOE and minion combat like a boss. Fail, and you’re incredibly far behind for playing a 3 mana 1/3.
I wish they if not included short action scene for Rainbow and Pinkie then at least gave them respective weapons: the point of the game is to be who you are not, so I doubt Pinkie really is a bard. Rainbow could be monk for all I know, but yea: hard to imagine with that outfit.
